what is the deffinition of nutrients?

Answer 1

A nutrient is either a chemical element or compound used in an organism's metabolism or physiology. Six nutrient groups exist and are broadly classified into those providing energy, and those used as components in the body or cellular structures.
A nutrient is essential to an organism if it cannot be synthesized in the organism and must be obtained from a food source.
Any classification of "nutrients" is likely to be arbitrary given the status of nutrition as a developing science. Researchers are becoming more aware of a wider range of nutrients essential for health.
Organism can metabolise organic compounds to use for their energy content, for structural purposes (growth or replacement of living structures), or for participation in chemical reactions necessary for life.
The discovery of the group of nutrients called phytonutrients reinforces the provisional nature of our knowledge. We know little about phytonutrients - organic compounds from plants - which play an essential role in the normal functioning of a body and have complex hormonal effects on health or play an active role in the amelioration of disease
